Connected Wellness Device Management App
Digital Fractal reengineered the mobile experience for Umay Rest, connecting a cross-platform Flutter application to a wellness device through Bluetooth Low Energy, device monitoring, firmware updates, health integrations, reporting, and notifications.
Move a connected-device proof of concept toward a dependable product.
Early-stage codebase
The existing cross-platform application required a technical audit before the team could confidently plan product improvements.
Reliable device control
The mobile experience needed stable Bluetooth communication for connecting to, controlling, and monitoring the device.
Firmware lifecycle
Supporting the physical product required a path for Nordic device firmware updates from the application.
Cross-platform consistency
The user experience and core device workflows needed to behave consistently across supported mobile platforms.
Useful wellness context
Health integrations, reporting, and notifications had to work together without turning the application into a diagnostic product.
Audit first, then rebuild the connected experience around the device.
A mobile product that coordinates app, device, firmware, and wellness data.
Bluetooth Low Energy
Connect the mobile app to the device for supported control and monitoring workflows.
Real-time device data
Transmit and present current device information within the mobile experience.
Nordic firmware updates
Support device firmware delivery through a managed DFU workflow.
Apple Health and Google Health compatibility
Connect supported wellness information to the health ecosystems available on each mobile platform.
Reporting and notifications
Turn device activity into understandable information and timely user reminders.
Design the software and hardware experience as one connected system.
Mobile application
- Cross-platform Flutter foundation
- Clear connection and device-state feedback
- Responsive reporting and notification flows
- Platform-aware health integrations
Device integration
- BLE communication and monitoring
- Resilient connection-state handling
- Nordic Device Firmware Update support
- Maintainable integration boundaries
Support wellness routines without presenting the app as medical advice.
The application connects users to the Umay Rest device and organizes supported wellness information. It does not diagnose conditions, replace professional assessment, or provide emergency or clinical care.
Production health integrations, privacy controls, consent, data retention, accessibility, and device-related compliance require deployment-specific review.
A maintainable connected-device application built beyond the proof-of-concept stage.
Digital Fractal combined a technical audit with cross-platform product engineering to create a clearer foundation for device control, monitoring, firmware updates, health compatibility, reporting, and notifications.
